Postcode Directories

Postcode Directories (for example the National Statistics Postcode Directory or All Fields Postcode Directory) provide a look up table of postcodes in the United Kingdom. The directory links them to a wide range of geographical units and other indicators. Fields cover administrative, electoral and census units. Postzon information, including a full UK National Grid reference is provided. Each entry also contains the date when the postcode was introduced or terminated.

From August 2012 onwards there are 2 different types of National Statistics Postcode Directories available for download. The Office for National Statistics Postcode Directory (ONSPD) Open edition, and the National Statistics Postcode Look-up (NSPL). The NSPL is also available with either lookups to 2001 or 2011 Census geographies. The method used to assign geographies to individual postcodes differs between the ONSPD and the NSPL. ONS provide a very readable ONSPD/NSPL Methodology document which describes these methodologies. Most academic users of postcode directories should continue to use the ONSPD. The NSPL should only be used by producers of National Statistics.
